| Zusammenfassung: | Endoluminal introducer sheaths and methods of forming the same are disclosed. The introducer sheath includes a first polymer layer, a second polymer layer, and at least two longitudinal support elements positioned between the first and second polymer layers. The longitudinal support elements are configured to provide columnar strength to facilitate advancement of the endoluminal introducer sheath into a vessel without substantial longitudinal compaction.
L'invention concerne des gaines d'introduction endoluminales et leurs procédés de formation. La gaine d'introduction comprend une première couche de polymère, une seconde couche de polymère et au moins deux éléments de support longitudinaux positionnés entre les première et seconde couches polymères. Les éléments de support longitudinaux sont conçus pour fournir une résistance colonniare afin de faciliter la progression de la gaine d'introduction endoluminale dans un vaisseau sans compactage longitudinal substantiel. |
